Date Fruit Production and Consumption: A Perspective on Global Trends and Drivers from a Multidimensional Footprint Assessment

Date production and consumption is mostly diffused in Middle East and Northern African countries. Date production is linked to the land and water footprint in countries where agricultural land and freshwater are scarce. We estimate the global land, green water, blue water, and water scarcity footprint at the country scale from a production perspective. We show that production trends are increasingly driven by foreign demand. By tracking the international trade dynamics of dates, we map the shift of environmental footprint from the producing to the consuming countries. We find that dates production and consumption are not yet decoupled from the associated environmental burden. Global dates consumption accounted for 1.4 million hectares of agricultural land, 5.8 Gm(3) of green water, 7.5 Gm(3) of blue water, and the related impact on water scarcity reached 358 Gm(3) world equivalent in 2019. The primacy of the economic driver is revealed, indicating that in the case of dates, the environmental sustainability aspects are currently overlooked for the sake of the economic benefit. The time-series analysis provides informative results to support policymakers in the design of mitigation strategies that can help the achievement of the SDGs

Data augmentation using background replacement for automated sorting of littered waste

The introduction of sophisticated waste treatment plants is making the process of trash sorting and recycling more and more effective and eco-friendly. Studies on Automated Waste Sorting (AWS) are greatly contributing to making the whole recycling process more efficient. However, a relevant issue, which remains unsolved, is how to deal with the large amount of waste that is littered in the environment instead of being collected properly. In this paper, we introduce BackRep: a method for building waste recognizers that can be used for identifying and sorting littered waste directly where it is found. BackRep consists of a data-augmentation procedure, which expands existing datasets by cropping solid waste in images taken on a uniform (white) background and superimposing it on more realistic backgrounds. For our purpose, realistic backgrounds are those representing places where solid waste is usually littered. To experiment with our data-augmentation procedure, we produced a new dataset in realistic settings. We observed that waste recognizers trained on augmented data actually outperform those trained on existing datasets. Hence, our data-augmentation procedure seems a viable approach to support the development of waste recognizers for urban and wild environments

The Effectiveness of Clinical Colloquium Established by the “Drawing Recall” Technique in University Counselling Services for Student Mental Health

An experimental assessment of the effectiveness of university counselling was conducted through the “Stress Drawing Recall” Technique applied before and after a clinical colloquium with 70 uni- versity students of both genders, aged 18 - 35 years, who had requested this service. Another 70 students waiting to undergo the colloquium were interviewed as a control group. Two parallel se- ries of drawings depicting personal stress situations were collected and, after evaluation by three expert judges in “double-blind” conditions, led to establishing five forms of development of the graphic language from the first to second drawing, defined as follows: a) distension, with a reduc- tion in stress indicators and increase in comfort indicators; b) explicit representation of conflict resolution; c) appearance of new elements, with persisting conflict; d) increase in stress indicators; e) invariant or equivalent repetition of the stress drawing. Results showed that students who un- derwent the clinical colloquium (experimental group) changed their stress drawings mainly in the direction of distension and conflict resolution, while the control group had more invariant or equivalent repetition of the stress situation ( X42 = 62.77; p < 0.001). The events depicted in the stress drawings were divided into three categories: a) limited short-term stressful situations due to mainly external agents; b) externally induced stressful situations with intense emotional reso- nance; c) wide-ranging long-lasting stressful situations with great involvement of the self. The participants were divided into: a) very anxious subjects; b) averagely anxious subjects; c) not very anxious subjects, on the basis of their scores on two questionnaires: the MPI (1959) and the STAI (1970). There is a correspondence between the subjects’ level of conflict and extension of the de- picted stress. This confirms the usefulness of the Stress Drawing Recall Technique in psychological counsellin

Acts of Commission: Lessons from an Informal Study - Discussion Guide

This discussion guide is designed to help you think through the concepts presented in Janice Nittoli's paper, Acts of Commission: Lessons from an Informal Study, and consider how you might apply them in the everyday practice of philanthropy.The guide contains four exercises:The first exercise provides a role-play to explore the match between a commission strategy and foundation goals and mission.The second exercise presents a template to plan a commission's membership, and assure that it contains a balanced and diverse group of decisionmakers.The third exercise involves creating a "History of the Future" to identify the combination of elements that lead to a successful commission.The fourth exercise offers a series of questions to help a foundation staff person prepare to work with a media consultant to promote a commission's work.Following the exercises, a resource page contains Nittoli's checklist to help funders assess their readiness to launch a policy commission

The biocapacity adjusted economic growth. Developing a new indicator

Abstract The environment may constrain economic growth potential. In other words, economic growth cannot be pursued in spite of ecological limits any longer. Here we present an economic growth indicator adjusted by taking into account the current tendency of national economies to overcome the availability of natural resources and ecological dynamics. We combine two indicators: 1) the Output Gap, a measure of production capacity of the economy based on the difference between actual and potential GDP, as a per cent of potential GDP; 2) the difference between the Ecological Footprint and the Biocapacity of a country, systemic indicators representing the extent to which a country operates within or beyond ecological limits. That combination gives rise to the Biocapacity Adjusted Economic Growth indicator which enables a categorization of countries based on assessment of growth patterns in line or not with sustainability principles

The ecological footprint accounting of products: when larger is not worse

One of the main goals of any (sustainability) indicator should be the communication of a clear, unambiguous, and simplified message about the status of the analyzed system. The selected indicator is expected to declare explicitly how its numerical value depicts a situation, for example, positive or negative, sustainable or unsustainable, especially when a comparison among similar or competitive systems is performed. This aspect should be a primary and discriminating issue when the selection of a set of opportune indicators is operated. The Ecological Footprint (EF) has become one of the most popular and widely used sustainability indicators. It is a resource accounting method with an area based metric in which the units of measure are global hectares or hectares with world average bio-productivity. Its main goal is to underline the link between the (un)sustainability level of a product, a system, an activity or a population life style, with the land demand for providing goods, energy, and ecological services needed to sustain that product, system, activity, or population. Therefore, the traditional rationale behind the message of EF is: the larger EF value, the larger environmental impact in terms of resources use, the lower position in the sustainability rank. The aim of this paper was to investigate if this rationale is everywhere opportune and unambiguous, or if sometimes its use requires paying a special attention. Then, a three-dimensional modification of the classical EF framework for the sustainability evaluation of a product has been proposed following a previous work by Niccolucci and co-authors (2009). Finally, the potentialities of the model have been tested by using a case study from the agricultural context
